A tsunami is a natural disaster that occurs infrequently but is
particularly devastating. It is often generated by earthquakes causing sudden
lifting or lowering the seabed, or volcanic eruptions, landslides in the
coastal ocean and some other causes such as meteorite impact... In the
framework of this paper we study tsunamis caused by strong earthquakes that are
capable of affecting the coastal areas of Việt Nam. This paper presents the preliminary
tsunami hazard maps in Việt Nam (scale!:
1.000.000). The tsunami hazard maps represent the maximum tsunami wave heights
at the coastline with the different time period base on the calculation of the
propagation of tsunami cause by tsunami earthquakes occur in subduction zone
Manila. Tsunami hazard maps are built according to the theory that Cornel
(1968) developed similar to the seismic hazard maps with three steps: 1) Define
the parameters of the tsunami sources; 2) Tsunami propagation modeling; 3)
Hazard mapping methodology. Findings dangerous tsunamis help us building early
warning systems to minimize tsunami disaster damage. This is also a valuable
source of information to serve the economic development planning tourism on
coastal areas of Việt Nam.
